Calculate the speed with which wafer emerges from a hole in a tank at

1.	Calculate the speed with which wafer emerges from a hole in a tank at which the gauge pressure is3 xx10^(5) N//m^(2) ?
Answer» Solution :Velocity of efflux = `V= SQRT( 2gh )` But`""P = h rho G or GH = ( P)/(rho.)` `therefore ""v=sqrt(2(P)/(rho))= sqrt((2xx3xx10^(-5))/(1000))= 24.49 m//s`
